Bug description

Application crashes with error message when trying to delete a text paragraphe in a table cell in a .docx file while “following modifications” is “ON for me and everyone” (the collaboration feature, not sure about the English name, my app is in French).

The error message is (again, original text in French) :

Warning. An error occured while working on this file. Use the option “save as” to save a copy on your disk.

How to reproduce

I cannot upload a file since I am a new user, instead I describe how to re-create it.

  1. Create a new docx file
  2. In the “Collaboration” tab, enable “following modifications” with “ON for me and everyone” (should also work with “ON for me”)
  3. Create a table and enter some text in some cell, with at least 2 paragraphs
  4. Save
  5. Make sure “following modifications” is still on “ON for me (and everyone)”
  6. Try to delete the last paragraph in the cell in a single shot by selecting the text then hitting backspace (do not erase character by character using backspace or del, this will not trigger the issue)

Note: I am not able to reproduce if the cell only contains one paragraph, thus the “at least 2 paragraphs” and “deleting the last one”

(sorry, I forgot to delete the template’s text…

Hello @Vincent.D,
Please still provide the screen recording of the issue reproduction steps (I’ve granted you the required permission). It is also highly recommended to test on the most recent 8.3 version

Hello, thank you for granting me the rights.

I confirm the issue is still present on version 8.3.0.97 (deb) (wich my Ubuntu-24.04 software updater automatically pulled this morning). Below are the screenshot and the test.docx file I use to reproduce the issue.

Please note the following :

  • the issue triggers while “following modification” is enabled, please make sure it is active before trying to reproduce
  • the issue triggered when I tried to delete the last 2 paragraphs in the cell, it did not trigger when I tried to delete the first two! Maybe it has something to do with tracking the modification of the “inserted table line” modification item or something like that?
  • the issue does not trigger outside of a table

EDIT : I also include a screencast below :
